At an average of 4 hours a session that would be 152 hours of GMing each month, or 19 man-days. You indicate above that you're charging a subscription for membership of your rotating games, so presumably this means that the players are paying for your time as GM.
As you say, what it looks like you need is a licensed VT engine to support your own sites' activities.
